Researchers from The
University of South Australia
and Baghdad's Middle
Technical University have
developed a cost-effective
alternative that may make
precision soil monitoring
simple and affordable in
almost any circumstance.
They successfully tested a system
that uses a standard RGB
digital camera to accurately
monitor soil moisture under
a wide range of conditions.
The system is based on a
standard video camera that
analyzes the differences in
soil color to determine moisture
content. It was tested at
different distances, times,
and illumination levels, and
was found to be very accurate.
The camera was connected
to an artificial neural
network (ANN), a form of
machine learning software that the
researchers trained to recognize different
soil moisture levels under different
sky conditions.

said Professor Javaan Chahl.
" Now that we know the
monitoring method is accurate,
we are planning to
design a cost-effective smartirrigation
system based on
our algorithm, using a
microcontroller, USB camera,
and water pump that
can work with different
types of soils. The system
holds promise as a tool for
improved irrigation technologies
in agriculture in
terms of cost, availability,
and accuracy under changing climatic
conditions. "
